MPOA (MultiProtocol Over ATM)

A specification (July 1997) from the ATM Forum (now merged

into the MFA Forum) designed to enhance LAN Emulation (LANE) by enabling interELAN communi-

cations without the intervention of a router, and the associated packet delay. MPOA provides high-performance, scalable routing functionality over an ATM platform, expanding on LANE, Classical IP over ATM (RFC 1577), and the IETF’s Next Hop Resolution Protocol (NHRP) in order to create a standardized notion of a virtual router within an ATM network. See also ATM, ATM Forum, Classical IP over ATM, ELAN, IETF, LANE, MFA Forum, NHRP, packet, router, and virtual.
